Paper subject to independent expert blind peer review. Dermal toxicity studies demonstrate that 24-hour exposure to a 12% (w/w) solution of SLS can increase the transepidermal water loss of the stratum corneum the outer most layer of the skin and cause mild yet reversible skin inflammation.24,25 Human patch tests (typically a 24-hour exposure) confirm that SLS concentrations >2% are considered irritating to normal skin.2,26,27 Dermal irritation also tends to increase with SLS concentration and the duration of direct contact.2 In reality, dermal exposure to SLS in cleaning products is more likely to last a matter of minutes rather than hours.9, Cleaning products that contain SLS have the potential to be dermal irritants if not formulated properly, but products that contain SLS are not necessarily irritating to the skin.28,29 Proper formulation development includes strategies for mitigating irritation (like adding cosurfactants) and can produce products with SLS that are mild and nonirritating to the skin. This contact allergy may cause your skin to react when it is exposed to this substance although it may take several days for the symptoms to appear. EE372: Sodium lauryl sulfate .
